Subject: [PATCH][RFC] ext3: Handle ext[34]_journal_stop() failure


Where are many places where xxxx_journal_stop() return code wasn't
checked. Off cause xxxx_journal_stop() failed very rarely (and usually
with fatal consequences), but this does'n meen it should not be checked.
For example most retry loops looks like follows:
ext3_journal_stop(handle);
if (err == -ENOSPC && ext3_should_retry_alloc(dir->i_sb, &retries))
goto retry;
It is realy insane do "retry" if ext3_journal_stop() has failed, because
this may increase damage in case of real problem.
